description

WP Post Author versions before 4.2.0 can allow unauthenticated users to change display-name, nickname, or website fields for the first user account, which is commonly an administrator account. Exposure requires front-end registration to be enabled with one of the affected profile fields declared in the registration form.

mitigation

Upgrade WP Post Author to version 4.2.0 or later. Until upgrades are complete, disable front-end registration or remove the affected profile fields from its registration form.

fixed in 4.2.0
